Generally, a cradle device is used to supply an external electrical power to a power supply unit in a portable terminal such as a PDA (personal digital assistance), or to put away and store the portable terminal that is not used. Recently, the portable terminal has been becoming more broadly used, since the portable terminal can allow a user to overcome the limit of the range of transmission and reception due to the increasing development of electrical communication. Accordingly, the cradle device of the portable terminal also needs an improved function. However, when the portable terminal is used in operations such as a computer or communication as the portable terminal is settled on the cradle device, there is inconvenience to the user because the portable terminal is used while settled on the cradle device with only a certain limiting angle.
In other words, as illustrated in FIG. 1, the user charges a portable terminal 80, or uses the portable terminal 80 by settling the portable terminal 80 on a cradle device 10 to supply the portable terminal 80 with electrical power. In the conventional cradle device 10 of the portable terminal 80, there is only a device to settle the portable terminal 80. Also, the conventional cradle device 10 has a simple structure to be connected with the external electrical power to supply the electrical power to the portable terminal 80.
When the portable terminal 80 is settled on the cradle device 10 having the above structure, the user experiences inconvenience in using the portable terminal 80, since the user can use the portable terminal 80 at only a fixed angle due to the cradle device 10. In other words, although the angle of a screen of the portable terminal 80 needs to be adjusted for such working conditions as light or a position of the user, the conventional cradle device 10 cannot adjust the angle of the screen of the portable terminal 80. Therefore, there is a problem that the user has to use the portable terminal 80 at a fixed angle of the screen.
SUMMARY OF THE INVENTION
Accordingly, it is the object of the present invention to provide a cradle device of a portable terminal allowing a user to adjust an angle of the portable terminal freely so that the user can see the screen of the potable terminal comfortably.

DESCRIPTION OF THE PREFERRED EMBODIMENT
Reference will now be made in detail to the embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to like elements throughout. The embodiments are described below in order to explain the present invention by referring to the figures.
Hereinbelow, a cradle device of a portable terminal according to the an embodiment of the present invention will be described in great detail by referring to FIGS. 2 through 4.
The cradle device comprises a cradle body 10, a holder 20 and a settlement unit 30. The cradle body 10 has a charge unit 60 to charge an electrical power to a power supply unit built-in a portable terminal 80, and a pen hole 50 to receive a pen, which is an input device of the portable terminal 80.
The holder 20 has a power supply unit 40 to supply an external electric power to the portable terminal 80, and a guide 70 to settle and provide ground contact to the portable terminal 80. The power supply unit 40 includes a power supply terminal 40 a to supply the electrical power to the power supply unit in the portable terminal 80, a PCB (printed circuit board) connection member 40 b connected with a PCB of the cradle body 10, and a cable 40 c connected with the PCB connection member 40 b. Here, the holder 20 is formed as a groove type holder to embrace a lower part of the portable terminal 80.
The settling unit 30 comprises a bracket hinge 30 a and a bracket shaft 30 b. The bracket hinge 30 a and the bracket shaft 30 b are rotatably connected to each other. In other words, the bracket shaft 30 b penetrates the bracket hinge 30 a, and a nut 30 c is connected with one end of the penetrating bracket shaft 30 b. At this end, a threaded portion of the bracket shaft 30 b is connected with the nut 30 c.
The bracket hinge 30 a is settled at the cradle body 10 by a pair of bolts 30 e. The bracket shaft 30 b is inserted into the holder 20 without using any separate elements to settle the settlement unit 30. In other words, a hole 20 a is connected with the bracket shaft 30 b by being engaged therewith without using any other elements formed at the holder 20. In addition, the bracket shaft 30 b is inserted into the hole 20 a and relatively rotated with respect to the bracket hinge 30 a. At this time, a friction member 30 d is disposed between the bracket hinge 30 a and the bracket shaft 30 b by a predetermined frictional force. Accordingly, the bracket hinge 30 a and the bracket shaft 30 b have a predetermined frictional force enough to settle the holder 20 while maintaining a set-up angle by the friction member 30 d, when a user adjusts the portable terminal 80 by rotating the portable terminal 80 settled on the holder 20 with respect to a predetermined angle. In this embodiment of the present invention, the bracket hinge 30 a and the bracket shaft 30 b of the settling unit 30 rotate the holder 20 by the frictional force. Yet, alternative operations that provide the same results may be used to realize the present invention. For example, a plurality of locking members can be provided to adjust the angle at different increments.
Hereinbelow, the angle adjustment operation of the portable terminal 80 settled on the cradle device will be described while referring to FIG. 5. The angle of the holder 20 embracing the portable terminal 80 is adjusted by the user. Here, the range of the angle adjustment of the portable terminal 80 is adjustable within a range of the rotation of the holder 20. In other words, the user can adjust the angle of the portable terminal 80 from line ‘A’ to line ‘C’.
According to the cradle device of the portable terminal 80, the holder 20 can relatively rotate with respect to the cradle body 10 by the frictional force of the settlement unit 30, thus the angle of the holder 20 can be adjusted. Therefore, the angle of the portable terminal 80 settled on the holder 20 also can be adjusted.
According to the present invention, when the portable terminal 80 is used while being settled on the cradle device, the angle of the screen of the portable terminal 80 can be freely adjusted with respect to the present working condition such as the light, and the position of the user.
Although a few embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes may be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the claims and the equivalents.
